Trialmaster fight: During his "pause" phase he just starts walking at me, without attacking.

Sadly I am unable to capture any footage of it, but twice in a row now, I have experienced this fight as a werewolf, where shortly after my freeze ends on him, he starts using his ultimatum pause where he is supposed to setup attacks around the arena, but instead, he just instantly stops it after about 1 second, and starts walking at me without attacking.


I am unclear what is causing this, as really the only thing I am doing to him is freezing him once rather early.
